Requirements

In order to use Exchange Online Archiving for Exchange Server, user mailboxes must reside on Exchange Server 2013 or Exchange Server 2010 (SP2 or later).

Federated identity and single sign-on

Administrators can use a single sign-on approach to Office 365 authentication with on-premises Active Directory. To achieve this, administrators can configure on-premises Active Directory Federation Services—a Microsoft Windows Server® 2008 service—to federate with the Microsoft Federation Gateway. After Active Directory Federation Services is configured, all Office 365 users whose identities are based on the federated domain can use their existing corporate logon to automatically authenticate to Office 365.

User subscriptions

Each user who accesses the Exchange Online Archiving service must have an Exchange Online Archiving subscription. Each email archive subscription can be used only for storage of one user’s messaging data.

Unlimited archive storage quota

The unlimited archiving feature in Office 365 (called auto-expanding archiving) provides an unlimited amount of storage in archive mailboxes. Each Exchange Online Archiving subscriber initially receives 100 GB of storage in the archive mailbox. When auto-expanding archiving is turned on, additional storage is automatically added when the 100 GB storage capacity is reached. For more information, see Overview of unlimited archiving in Office 365. See the Office 365 Roadmap for details about availability.

Feature availability across Exchange Online Archiving plans

注意事項：

1   User mailboxes must reside on Exchange 2010 SP2 or later. 2   In-Place Archive can only be used to archive mail for a single user or entity for which a license has been applied. Using an In-Place Archive as a means to store mail from multiple users or entities is prohibited. For example, IT administrators can’t create shared mailboxes and have users copy (through the Cc or Bcc field, or through a transport rule) a shared mailbox for the explicit purpose of archiving. 3   For a list of supported Microsoft Outlook versions, see Exchange Online 封存中的用戶端功能. 4   Azure 版權管理 (RMS) isn’t included, but can be purchased as a separate add-on in order to enable the supported IRM features. 5   Windows Server AD RMS is an on-premises server that must be purchased and managed separately in order to enable the supported IRM features. 6   When you put a mailbox on In-Place Hold or Litigation Hold, the hold is placed on both the primary and the archive mailbox.
